JDBC Tutorial in Java: Architecture, API, and Real-World Examples
JDBC (Java Database Connectivity) JDBC (Java Database Connectivity) is a standard Java API that allows Java applications to communicate with a database server. It provides a set of interfaces and classes used to connect to databases, execute SQL queries, and process results. JDBC is part of the Java Standard Edition and is available in the java.sql package, which is included in the rt.jar file. Since it is part of the Java built-in libraries, programmers can directly use JDBC by importing the required classes. What JDBC Does Establishes a connection between a Java program and a database Executes SQL queries (SELECT, INSERT, UPDATE, DELETE) Retrieves and processes data from the database Manages database transactions JDBC API Structure The JDBC API consists of interfaces defined in the java.sql package. These interfaces are implemented by database vendors (such as MySQL, Oracle, PostgreSQL) through JDBC drivers. The JDBC driver acts as a bridge between Java applications and the database...
